Quantum coherence in an all-solid-state dye-sentizied solar cell

Abstract

The reported new type of all-solid-state, inorganic solar cell will be discussed by a semiclassical light-matter interaction method. The molecular compound will be treated by a three times two-level coupled quantum system. The equation of motion of the density matrix of this system will be analytical solved, in linear approximation and due to the coherent superposition of certain states, time-independent off-diagonal elements will be obtained. These elements represent an important components for the overal optical performane of this cell.
